Help please. There is a class that reads the numbers in the text file "in.txt" and assigns them to the coefficients of a, b, c, d. Next, you need to implement a class that computes the function: y = (int) (a * Math.pow (x, 2) + b * x + c * Math.pow (x, -2) + d). The result must be displayed on the screen and in the text file "out.tht." In organizing the I / O to be used try-catch mechanism to catch exceptions of type IOException. Also need to write a variant in which the main program waives the exception handling with throws.
